To all whom it'mag mm:

Be it knownthat I, CHARLEsJS. Sin-(DER,

acitizen of the United States, residing-at" Phila delphia,-in the county of Philadelphia,

and State of Pennsylvania, have invented certain new and useful Improvements in V Heaterstof which the following is at speci- One object of my invention is to'in'ake an improved heater which ca 'n be used asfa oneiroom heater and as such vcan be made in a form so as to be readilytportableand conveniently'connected by a gas hose so 'as' fto' t supply gas to the burner'for creating heat.

Another object is to nake my improved heater of a 'simplefdurable and neat construction which can be readily nanufactured;

niadein' accordance with} my invention,"

Referring to theldrawings, 12 represents a circular base forming a part vof my improved heater; saidbase including a circular bandilir preferably, made ofsheet metalhav ing holes leaextending therethrough'above its bottom; said holes beingspaced apart andallowing air to enter the space within the base-when the-baseis set upon a floor The lower edge of the band is preferably:

These objects, and other j advantageous ends-which will be described'hereinafter, I attain in the following "manner, reference being had to th'efaccom'panying drawings in, whioh v g 1 I intermediaterib 18,

Figure l is a front'elevation of; aheater cylindrical section 23 of copper, preferably plan view taken on plate 16 so as to snuglysurround-the iiiturned so as to providea reinforcement and if desired a core wirekl5 can be insertedwithin the turned "portion for strengthening purposes. *The upper end of the band 13. is vben't in embracingposition' around the outer edgefportionlof acircular base plate 16; said baseplate being 'preferablymade of cast metal and having three upwardly projecting circular ribs 17, 18Ia'nd 19; these ribs being made concentric; the rib-17 being innermost and the rib 18 being positioned between the ribIT and, the outer. rib 19.;"

An outer a cylindrical shell or: jacket 20,

"which isjpre'ferably madefofshe'et metal, has 1 its lower edge supported on the top of the base plate 16 immediately surrounding. the r'1b19 so astosnugly fit around saidrib 19.

- Anfintermediate shell 21,; which is jinade cylindrical and f preferably of'sheet metal; is positioned withinjthejouter shell 20 and has its lower edgev supportedon the top. of 'w the base plate .16 andsnuglysurrounds the a An inner. cylindrical drum. 52 includes a sheet, copperyand this, section is positioned drum 22. This pedestalsection is .n ade in Y supportedfon the top suriface ofthe base nern ost rib' 17. A burner supporting partltion 25 is made in the form of a p'late in partition "25 to, the pedestal section 24. The

drum section-23 has tongues 27. in theform of small plates which are attached thereto} ed to extend through slots 28; in'the partition 25 so as to prevent relative rotation or dru n'22. At the same time itwill be noted thatthecentral drum can bereadily lifted the form of a cylinder, with itsloweredge i flange 30 which-rests on the upperedge of the jacket 20 the inner perforated body apart from thepedestal section-2t'wheniit is 7 portion 31 of said top plate fitting within the upper portion of said jacket and resting upon the top edges of the intermediate shell 21 and the. drum 22. This top plate has circular flanges 32 and 33 which respectively depend within and. fit the intermediate shell 21 and drum 22 so that said shells and drums will be kept in proper spaced position at their tops as well as at their bottoms. Tie bolt rods3l extend through the topplate 29 and base plate 16and have nuts on their lower ends whichengage the lower surface of the base plate within the confines of the base band 13; the upper ends of the tie bolt rods being provided with heads which fit countersunk portions in the top plate 29. 'Thetie bolt rods preferably-extend through the space between the outer and intermediate shells and'thereby hold the base plate and top plate together and also serve to prevent the jackets and drum from moving vertically. I .e

Theperforations in the top plate 29 extend. over 5 the spaces between the shells, the

' drum and the intermediate shell, and the spacewithin the drum 22. The intermediate 7 shell has elongated'notc'hes 35 whichextend upward and. form, communication between the lower part of the spa'ce36'bet'we'en the shells and with the lower part of the space 37 between the intermediate shell and the drum at positions above thebase plate 16.

' The pedestal section 24 of the drum 22 has holes 38 which formcommunicationwith the space-iwithin the pedestal section and the lower partof the space 37. The partition 25 has holes39 which form communication with the space'within the pedestal section l 24 and the space within the section 23.

7 A burner 40 is positioned within the sec tion 23 of the drum 22' and rests on the top of the partition 25; said burner'having" a bolt 41 which extends through the parti- 7 tion and is secured by a nut 42 within the pedestal'section, which. engages the under surface ofsaid partition, This burner 40 has a supply tube or stem 43 which projectsoutward through an upwardly extending notch {id in the lower end of the section 23 of the drum and through holes i5 and 46 in the shells 2O 'and'21.

extension 48 for supply hose:

The shell 20 has an aperture 49 which serves as a doorway which canbe closed by a sl-idable door 50 movablein guides 51 which are secured to the outer surface o'f'the shell -20, as clearlyshownin Figure 1.- The intermediate shell 21 has a horizontally elongated-slot 52 directly inward from the door aperture 49' and the section 23 ofthe drum 22* has; a smaller hole 53-incentral registry This tube, at a position outside of'the jacket 20, preferably includesan air regulating shutter 46 and a gas inlet valve 4c7saidvalve having an the connection ofagas" with the slot 52. The arrangement is such that a person holding a lighted-match in their hand can insert the hand through the aperture 49'; the fingers' extending through the slot 52 and the match extending through the hole 53'so that the flame of the match can be held near the burner when it is desired to light the same.

The heat deflecting and radiating hood 54, which is preferably made of sheet copper and of conical formjwith theapexpointdrum so that there is. a space surrounding the peripheral edge5-7 oflthehoodtthe hood also preferably being perforatedv as shown A suspension bolt. 59-v passes centrally through. the hood 54:. andat its. lower. end:

supports a disk 60; said. disk, being; posiitioned directly above and spaced from the burner 40. The disk 60. has.spacing fingers 61 extending, radially therefrom,;as. shown in Figure 5, for engagement with the inner wall of the drum section. 23. The suspen-. sionbol't'59' projects through an upturned boss 62-and hasa nut 63 on. its lower end below the disk so as to support the diskin a position belowthe hoodfj543 A core of fire brick or other refractory material 64:. has a hole through which the suspension bolt 59passes, said core 64', being positioned above the disk 60- and resting on the boss 62. Thus the core 64' is positioned between the disk 60 and the hood 54. As illustrated, I have shown the top of the core or block 6&- provided with transversely extending grooves 65 immediately below the. hood 54; thus forming an: extended radiating surface for heat absorbed from the burner 40. The

outer surface of the core 64 preferably tapers-downward from a. size of" greater diameter than the disk so that the heatfrom the burner will be deflected by the upwardly flaring outer surfaceof the disk toward the copper. drum section 23 and the heat encountered by the lower part of the hood wlll' be partly deflected, radially into engagement with the copper section 23" of the drum and thus the drum ,willibecome; ex; tremel'yhot during th'euseofthe heater a'nd the heat radiated jwwill pas's' upwardly through the: space 37 between. that-drum and the shell 21'; the space"36fhaving airtherein" which is Y comparatively cool. Thus com-' .paratively cool" air will pass downward" through the-perforated plate 291 into the; space 36 and? will pass intothe space: 3??

throughthe notches This air will ab sorb the heat radiated from the drum and will pass upward through the space 37 and outward through the perforations in the plate 29 immediately above thespace; 3?.5; I also preferably provide holes 66 in the drum section 23 at a level below the edge, 57

of thehood 54 so thata portion-of the heated w lldirectly pass through the holes 66 into.

the spa'ce 37 and will-then pass out through direct heat through the holes 58, will pass directly from the interior of the drumsec-Q tlon 2-3 outthrough theperforations int-he top plate 29. Also'a certainportion, of the heat will pass between the edge, 5 7 and. the

' inner wall of the drum sectionp23'and this heat will also pass directly cutthrough the perforations of, the top: plate 29, It will be n o ted that aportion oft-he air from the bottom part of the spaces 3,6and 37 will pass into the pedestal; section through; the holes. 38; and will thenJpas's; upward r through ,the

holes 39 into the drum seetion 23jwhe're it will Lbeco" e heated.- and 7 pass upwardl through the drum @section 7 By making the hole 45 inthelower end of the intermediate shell 21 in}: the form :of 1a notch oflthe same general characte'r-as 'onefQ Q of" the notches 35, it is an easy matter to" assemble the parts since the pedestal s'ecti'on' 24s with the burner thereon can be positioned on-thebase plate 16,-atter whichthe section 23,;canbe lowered, the r the intermediate: shell 21" can be lowered into {position andfinally 'the outer shell 20 can be positioned so thatthe'extreme outer end of the tube 43 will'register withthe hole 4e. and then the nipple .connectioufortheair adjuster and valvecan be applied by'screwing the same 1 into the end of the burner tube43. The several parts can be quickly assembled and c in the-actual-use oftheheaterl have found that great heat can be secured at a lowcast: i Furthermore by arranging the base and pro-v vidingthe holesil l, the -space below the base plate willfbe kept comparatively cool so that the heater canjbe set directly on a floor and the base will becomparativelycool e I V 'and .the.outershell there being air passages from the lowerpart otthe outer space to the-intermediate space, and iromthe interat all times. a
